The Original Under Sink Mat Silicone Waterproof Drip Tray Liner (Trimmable) up to 34" x 22
Product description
What it is and what it’s for
If you’ve ever had a small plumbing leak, a spill from cleaning products, or a surprising mess under the sink, you already know the problem: water damage can spread fast into cabinet bottoms and the floor area underneath. The Original Under Sink Mat is a silicone waterproof drip tray and cabinet liner designed to catch that runoff before it soaks into wood or particle board.
On paper, the pitch is pretty straightforward—use a flexible mat with a raised lip to contain drips, then wipe it clean. It’s also trimmable, so you can adjust the footprint for different sink cabinet sizes and odd layouts.
Key features that actually matter
The biggest practical win here is the combination of silicone flexibility and a raised edge. The mat is described as BPA-free premium silicone and it’s marketed as safe around people and pets. The raised lip is meant to keep water (and spills) from running straight off the bottom of your cabinet area.
Flexibility matters more than people expect. Instead of forcing a rigid tray into place, the mat can be folded to fit around pipes and other obstacles. The brand also notes that you can cut it with scissors or a utility knife to fit around pipes—so you’re not limited to a perfect “square and straight” installation.
It’s also designed to stay put without you needing to seal it. Since it can be trimmed and it’s flexible, it should lie flatter in real cabinets, where everything is never quite symmetrical.
How trimmable sizing helps (and where you might need to measure twice)
This under sink mat is listed as measuring 34 inches wide by 22.5 inches deep, and it can be trimmed down. The entry states width can be trimmed to 30.75 inches or 28 inches, and depth can be trimmed down to 20.75 inches to fit for 31" or 28" kitchen and bathroom sink cabinet setups.
In practice, the “it’s adjustable” benefit comes with a simple reality check: you’ll want to measure your cabinet base and the sink cutout/pipe area before you start cutting. Once you trim silicone, you can’t un-trim it.
Also note a potential limitation: while it’s designed to fit “under sink” and “under bathroom sink mat installation,” it’s still a tray-liner approach. If you’re dealing with a major leak scenario beyond what a mat can physically contain, you’ll still need to address the source quickly.
Everyday use: what it feels like day to day
For routine messes, the use case is pretty clear. When water drips or a small spill happens, the raised lip is meant to hold it on the mat so you can handle it without immediate cabinet panic. The brand also claims it holds up to 1.5 gallons of water, which (if accurate for your exact situation) gives you some extra time.
A concrete example: after rinsing a messy sponge under the faucet, you notice moisture pooling where the cabinet base is. With a mat like this, you’re not scrambling to dry warped wood—you can lift or pull back to inspect, then wipe the silicone clean.
For cleaning, the entry says it wipes clean instantly and is easy to maintain, with the mat removed for washing.
What else you can use it for (multipurpose angles)
The listing positions it as more than just an under-sink protector. It can be used as a cabinet liner, pet feeding mat, or even a dog bowl mat thanks to the large surface and raised edge concept that helps keep food and water on the mat.
It’s also suggested as a disinfection mat surface for shoes or other utility uses. That’s one of the reasons this type of silicone liner can be worth owning—if your goal is “wipeable, waterproof surface,” it can pull double duty.

Pros and cons to keep in mind
What stands out: - Flexibility for tricky pipe areas, plus trimming to match your cabinet size. - Raised lip approach aimed at keeping drips and spills contained. - Easy maintenance—wipes clean quickly and removes for washing.
Where it may fall short: - Because it’s trimmable, you’ll need to be careful with measurements before cutting. - It’s meant to protect from leaks/spills, not replace fixing the underlying plumbing issue—so if you have recurring water problems, you still need to address the cause.
Should you buy it?
Buy it if you want a waterproof under sink protector that’s flexible enough to handle pipes, and you like the idea of tailoring the mat size for your cabinet base. It makes sense for kitchens and bathrooms where minor drips, routine spills, or disposal-related messes could otherwise sit directly on cabinet bottoms.
Skip it if you’re expecting a rigid, perfectly pre-sized tray with no trimming involved, or if you already know your space doesn’t align with the listed dimensions and trimming ranges. Also, if you’re dealing with a severe leak situation, treat this as containment for the meantime—not a permanent solution.
